| Outline of Final Research Achievements |
In recent years, the magnetic targeting of delivering drugs encapsulating magnetic nanoparticles (MNP) to target sites by utilizing an external magnetic field and magnetic hyperthermia treatment which kills cancer cells by applying an alternating magnetic field from the outside are attracting attention. In order to increase the effectiveness of these therapies, it is necessary to visualize the spatial distribution of accumulated MNPs and accurately quantify the accumulated amount. Recently, we have developed an imaging method of MNPs called magnetic particle imaging (MPI) and the device. Then, we developed a system to optimize the effect of magnetic targeting and therapeutic effect of magnetic hyperthermia treatment using our MPI method, and investigated the usefulness of the system using phantom and animal experiments. As a result, it was suggested that the developed system is useful for optimizing the effects of magnetic targeting and magnetic hyperthermia treatment.
